Structured rehabilitation lifted weaning success in ventilated over-80s from 12% to 45%

Design

Single-centre, assessor-blinded randomised controlled trial

Population

150 patients aged 80 or over on prolonged mechanical ventilation, Beijing

Primary outcome

Successful weaning

Effect

45.3% vs 12.0%; adjusted HR 5.11 (95% CI 2.46 to 11.23)

This single-centre, assessor-blinded randomised trial in Beijing enrolled 150 patients aged 80 or over on prolonged mechanical ventilation, allocating 75 to a multicomponent pulmonary rehabilitation programme and 75 to standard rehabilitation.

Successful weaning occurred in 45.3% with the multicomponent programme against 12.0% with standard care (adjusted HR 5.11, 95% CI 2.46 to 11.23); a competing-risk analysis gave a similar result (subdistribution HR 4.45). The intervention group did better on oxygenation off the ventilator, diaphragm thickening, cough strength and muscle strength, and had less ventilator-associated pneumonia at 60 and 90 days. Deep vein thrombosis and 90-day mortality did not differ (2.7% vs 4.0%).

Very old patients on long-term ventilation are often assumed to have little prospect of liberation. This trial suggests structured rehabilitation can change that, though a single centre with a large effect needs replication.

• Consider a structured, multicomponent rehabilitation programme for older patients on prolonged ventilation rather than standard care alone.
• Include respiratory muscle, cough and limb strength work in the programme.
• Track diaphragm function and cough strength as markers of progress.
• Do not assume age over 80 alone rules out successful weaning.

Why it matters

It challenges therapeutic nihilism about the oldest ventilated patients.

Don't overread it

Single-centre with 150 patients; the size of the effect needs confirmation elsewhere.

The statistics, in plain English

A hazard ratio of 5.11 means patients in the programme were weaned about five times faster over follow-up. The wide interval (2.46 to 11.23) reflects small numbers, so the true effect could be considerably smaller.
